WATER-LEVEL.

Specification of Letters Patent.

To all ywhom 'it may concern:

Be it known that we,

J oiiN Kasimir and Run F. BERAN, citizens of the United States,

residing at Moulton,

in the county of Lavaca,

State of Texas, have invented certain new and useful Improvements indeclare the following to be and exact description ot the inand we dohereby a full, clear,

Water-Levels vention, such as will enable others skilled in the art towhich it appertains use the same.

to make and This invention relates to leveling instruments and it hasfor construjction that may a level at widely distant points or in deingtermining inclination its object to provide a be used for determinsunder the same conditions and furthermore to provide an instrument whichmayY be correctly read under such conditions as where it cannot erectposition.

Figure l is a side one ot' the gages being Fig. 2 is a sectiona Fig. 1.

Fig. 3 is a sectiona Fig. 1.

1g. t is a section on be held in elevation of the device,

shown in section. l view on line 2-2 ot l view on line 3 3 ot line 4:-4ot' Fig. l.

T he device comprises a pair ot glass gages 1, and since they areidentical in construction a description of one will sutiice Jfor both.

Each gage comprises tube being connected said sleeve having an ing 4formed therein so a glass tube 2, said in a metallic sleeve 3, elongatedsight openthat the level of the 3 is a cap 5, said cap having an annularshoulder 6 formed therein, said shoulder serving to engage the packingring 7 so as to hold the same firmly engaged with the upper end of thetube 2. compressed as The packing ring can be desired since the cap 5 isthreaded upon the sleeve.

Carried by the cap 5 is a valve 8, which can be operated to permit airto escape from the tube 2 so as to break the vacuum therein, thuspermitting-the liquid Threaded upon the 3 is a coupling annular shouldering the packing ring with the lower end o 9, said coupling l0 formedtherein 11 in tight engagement to rise and fall freely. lower end ot thesleeve having an for holdt the tube 2 when the Patented A ug'. 17, 1920.

coupling is secured tightly upon the sleeve. The couplings 9 areprovided with reduced extensions l2 which are engaged by the ends of theliexible tube 13, and to hold the ends of the tube engaged on theextensions clamping bands 14 are employed.

Since the gages l are connected by the tube i3 it is obvious that thesame can be moved and that the differences in the height of objects canbe readily ascertained.

lt will be of course understood that graduations are provided so as todesignate the differences between the heights of `ioints, and thesegraduations can be marked upon the tube or upon the sleeve, as desired.

A combined inclinometer and level attachment is provided forlone of thegages and consists of a frame l5, said frame having a vertical arm 1Gand horizontal arms 1T which are connected with the cap 5 and couplingS). Fixed centrally ot' the arm lo is a block 18, saidhlock serving tosupport one side of the circular band 19, the other side ct which isfixed to the sleeve 3, said band having marked thereon suitablegraduations. Also supported by the block 18 is an arm 20 to the innerend of which is pivotally connected a casing 21, said casing havingpointed ends Q2 which co-act with the graduations so as to indicate thenumber ot degrees between the inclination and the horizontal, saidcasing having mounted therein a spirit tube 23 which when at rightangles to the gage will enable a level to be determined accurately.Since the casing 2l is pivotally mounted it is obvious that the same canbe adjusted to any desired angle.

It will be noted that the lower end of the coupling 9 includes a valvecasing 24 in which operates a valve Q5. Thus it will be seen that thewater in this gage can be transferred to the other gage and the valveclosed, after which the coupling 9 can be remove from the casing 24since said coupling is screwed into engagement therewith, as at Q6,thereby permitting the attachment to be used separately. After the valveis closed it is obvious that the fluid will be trapped in the tube 13and the other gage.

lu one use of the apparatus, the two ends are held side by side andadjusted with respect to each other until the water level in both tubesregisters the same on their respective scales. One tube is then held invertical position with this identical point that has been read on thescale at the known level. The other end oi the apparatus is thenmanipulated into vertical position until its water level is on the sainepoint oi' its seule as formerly. later level in that tuhe will indiwale:1 point :it the Same altitude as the known point.

At times, the head room may not permit of the tuiles being' heldvertical in the determination of the second point. Under suoliCirenrnstanees.y when the known point is lo cated Where head room islimited, the two tuhes are pnt side by side as in the first instance andare held :it such inclination as the head room will permit and with theWater level in both tubes at the known altitude point. The indication onthe scale ot the spirit level on one ot' the tnlies is then noted so asto read the inolination ot the tubes. The tulle having the spirit levelis then om ried to the remote position and. is tilted so that the spiritlevel scale will read exaetly the same as formerly and is furthermanipulated so that :it sufh inclination of the tube. the wa ter levelin that tube will read the saine :is just previously. The point at Whiehthe spirit level will show the same inclination as formerly and with theWater level the same as formerly, is the point Whose altitude is thesame as the altitude ot the known point.

Ot course, ii 'the place at which the altitude point is to he determinedis the one that lacks head room, the inelinution :it whioh the two watergages are to he read, is determined at that place.

What is claimed is:-

The eon'lhination with a pair oi gages :ulapted to contain liquid, and aiexibleY tube connecting the gages ot a frame having its ends engagedwith one of the gages, an annular member Carried by the treme anddisposed between the same and the gage and havinpr graduations thereonforming;r e seele, an arm extending' from the annular member toward itstenter, a pointer pivot-ed to the erm and havingits extremities movableover the sealeand a spirit level within the pointer and exposedCentrally thereof.

ln testimony whereof, We affix our signen tures in the presenee ot twowitnesses.
